Being a great fan of Jarre (who aint?), I've allways wanted to recreate that E310U organ sound, that Jarre used so much on his first albums... I've tried pretty many things, and have come pretty close, but not quite...
I know that you jarre freaks will tell me, that I'll have to get the real thing



Now... the thing is hard enough to recreate using most synthesizers, as that darn thing has only one amp envelope goin' for no matter how many keys you press... not many synths will recreate that feature.
... BUT...The hardest part of the recreation I find to be the modulation unit... I've looked on the schematics of the Solina String Ensemble (which is basically the same as unique... almost), and I unfortunately cannot understand those old ways of drawing signal paths etc. but it seems like the modulation section (chorus) is rather complicated... involving the raw signal being modulated in pitch 3 times (3 stage chorus), but it involves a lot more than just that... it has some tremolo modulation and phase reversion of some of the stages as well... basicaly I'm right now trying to recreate just that modulation unit... but as I see it, nothing in terms of real FX units old and new do this type of modulation... anyone know of something similar? that chorus sound is really fat and very special for the right tone on the Jean sound... you can check this site for MP#'s of the effect:

I've been thinking that this chorus might be recreatable in some modular synth like the Modular G2 or equal... I don't need info on the phasing part... it's done with an Electroharmonix smallstone running at lower voltage... that's allready done, and working fine

So to recreate the sound (as close as possible) you'd have to have the following (and in the same order):
1. Simple polyphonic Saw Oscillator (simple gate)
2. Global Amp envelope (legato style)
3. 3 stage chorus modulation unit
4. EH Smallstone Phaser
5. Delay unit.
That should be it, exept that some filters are thrown in on various places in the signal path of the E310U also, but they are easily fixed.
So I guess that the question here is; Does any of you know the signal routing of the E310U's modulation unit? ... the schematics are downloadable from the net here:
http://www.retrosound.de/Solina.html
Maby someone with more electrical knowhow can decipher that diagram, and explain what signal goes where and how?... currently it looks like everything is connected to everything in that darn modulation curcuit!

It's the last brick in my puzzle missing

Now, I know I'm probably asking more that what the avegare musician need or want to know, but hey!... maybe there are just a few Jarre geeks in here, who know something... MARCEL? O2?
